Mass Producing Art That Sells Or Creating From The Heart

We discuss a series of questions about production of art " From a spiritual standpoint I understand that we are here to share our gifts but I feel so drained and depleted through years of keeping up with repeat orders that I want to do my own thing and create from the heart but I am feeling guilty about it.. Is this wrong? Is there something I don't understand about being in service to others and how can we follow our bliss when we don't want to create the things that others want.. I think I once heard you say to "create what you want to create" I just want to play... and I do now!!.. yes things take longer to sell but I am much happier and my work is improving!.. something I am sure would not have been the case if I continued on the drudgery path.... Am I being selfish?
